GAS-RANGE.

SPECIFICATION forming part of Letters Patent No. 702,434, dated J une 17, 1902.

Application filed April 11, 1901, p Serial No. 55,414. (No modelJ To @ZZ whom t muy concern: 1

Be it known that I, WILLIAM DRIVER HUT- SON, of the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Gas-Ranges; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to certain new and useful improvements in that class of gasstove in which the ovenis heated by a burner or burners located in the lower part of the stove. Heretoforeithas been customary to locate the burner or burners in the lower part of the oven and use the circulation ofthe heated products of combustion to cook the contents of the same. The principal objection to this construction arose from the liability of the contents to become charged not only with the odor of the gas, but also with a comparatively large quantity p of carbonic-acid gas during the cooking process, which had a tendency to destroy the iavor of the contents, especially in the case of meats and pastry.

The object of this invention is to so construct the gas-stove that the gas and the products of combustion from the burner will be prevented from entering the ovenand the heating value of the products of combustionbroken away to show the position of the lines. t

Fig. 3 is an enlarged perspective view, partly in section, of oneof the burners. Fig. Li is a crosssectional view of the same.

Like letters ofreference refer to like parts throughout the specication and drawings.

The gas-stove consists of a series of ovens a, a', and a, inc'losed in an outer casing b, the top of which is provided with a series of holes c and c for kettles, pots, and other kitchen utensils. Between the ovens a and a. is a Vertical iiue d, and between the ovens d' anda is a vertical iiue d', the upper ends of the iiues d and d being opposed to the holes c and c in the casing b. Located below the bottoni c of the ovens and opposed to the lower ends'of the iiues d and d' are a series of burners f and f', respectively. Each of the burners fand f is connected with a gas-supply pipe g and is fitted with a valve 7i, to control the passage of the gas from the supply-pipe g. Each of the burnersfandf' consists of a metallic tube t', the length of which preferably exceeds that of its respective iue, `and in the top of each tube i is an elongated narrow slot] for the emission of the gas, and covering the slotg is a wire hood k of a fine mesh. Connected to the ends of the hood 7s are collars l, which encircle the tubez for the purpose of maintaining the hood 7,:

in its proper relative position to the slot j. Inclosing the tube, hood, and collars is a protective casing m, provided with a slot o, registering with the slot j. The burners f and f' are located at the lower ends ot' the lines d and d', respectively. The heat ascending from the burners through the flues to the top of the ovens is distributed across the topof the ovens by the vessels or lids covering the holes c and c. Located between the holes c and c' is a partition p, which eX- tends from the underside of the outer casing bto the top of the oven a to concentrate the 'heat below the holes c or c', respectively, when only one burner is in use. By construct- `ing the stove in this manner the heat from the burner or-burners can be utilized for the purpose of heating the oven or ovens and subsequently used for the purpose of heating akitchen utensil placed on the casing or over the hole in the top of the same.

Again, by providing the ovens with the vertical flues and locating the burners below the bottom of the ovens and permitting the gases to escape from the burner through the flues the gas' and products of combustion are prevented from entering the oven and the heat units in them are absorbedinto the casing of the oven during the passage of the products of combustion through the flues. Located below the center oven a is a plate-warmer IOO a3, heated by radiation from the burners f when ignited heats the wire hood to incandescence. Part of the products of combustion pass from the burner across the oven-bottom. The remainder rise through the Vertical lues and heat the sides of the same during their ascent. After the products of combustion reach the top of the flue they circulate across the top of the oven in the space q, formed between the oven-top and casing, heating the top of the'oven, the casing, and the kitchen utensils thereon. By this means the bottom,

sides, and top of the oven are evenly heated f by the products of combustion from the burner below the oven and the casing and the kitchen utensils thereon are simultaneously heated by the saine products of combustion.
